Ndị ntụgharị fotovoltaic nwere ụkpụrụ teknụzụ siri ike dị ka ndị ntụgharị nkịtị. Onye ọ bụla inverter ga-ezute ihe ngosi teknụzụ ndị a ka e were ya dị ka ngwaahịa tozuru oke.
1. Mmepụta Voltaji kwụsie ike
Na usoro fotovoltaic, ike eletrik na-emepụta site na anyanwụ na-ebu ụzọ chekwaa ya site na batrị, wee gbanwee n'ime 220V ma ọ bụ 380V nke na-agbanwe agbanwe site na inverter. Otú ọ dị, batrị na-emetụta ụgwọ ọrụ na nkwụsị nke ya, voltaji mmepụta ya dịgasị iche iche. Dịka ọmụmaatụ, maka batrị nwere 12V ọnụ, ọnụ ahịa voltaji ya nwere ike ịdịgasị iche n'etiti 10.8 na 14.4V (ịfefe oke a nwere ike imebi batrị). Maka onye ntụgharị nke ruru eru, mgbe ntinye voltaji na-agbanwe n'ime oke a, mgbanwe nke voltaji na-emepụta ihe na-eme ka ọ ghara ịfefe ± 5% nke uru a kwadoro, na mgbe ibu ahụ gbanwere na mberede, ntụgharị voltaji mmepụta ekwesịghị gafere ± 10. % nke uru akwadoro.
2. Mgbagha nke Waveform nke mmepụta voltaji
Maka ndị ntụgharị sine ebili mmiri, a ga-akọwapụta oke mgbagha ụdị ebili mmiri anabatara (ma ọ bụ ọdịnaya kwekọrọ). A na-egosipụtakarị ya dị ka mkpokọta waveform ntụgharị nke voltaji mmepụta, uru ya ekwesịghị gafere 5% (mpụta otu usoro na-enye ohere 10%). Ebe ọ bụ na elu-usoro harmonic ugbu a mmepụta site inverter ga-n'ịwa ọzọ losses dị ka eddy ugbu a na inductive ibu, ma ọ bụrụ na waveform distortion nke inverter bụ oke ibu, ọ ga-eme ka oké okpomọkụ kpo oku nke ibu components, nke na-adịghị mma ka. nchekwa nke ngwa eletriki ma na-emetụta usoro ahụ nke ọma. arụ ọrụ arụmọrụ.
3. E gosipụtara ugboro ugboro
Maka ibu gụnyere moto, dị ka igwe ịsa ahụ, friji, wdg, n'ihi na oge kachasị mma nke moto bụ 50Hz, ugboro ole dị elu ma ọ bụ dị ala, nke ga-eme ka ngwá ọrụ ahụ kpoo ọkụ ma belata ọrụ ọrụ na ndụ ọrụ. nke usoro. Oge mmepụta kwesịrị ịbụ uru kwụsiri ike, na-abụkarị ike ugboro 50Hz, na ngbanwe ya kwesịrị ịdị n'ime ± 1% n'okpuru ọnọdụ ọrụ nkịtị.
4. Ibu ike ihe
Mara ikike nke inverter ibu ibu inductive ma ọ bụ capacitive. Ihe na-akpata ike ibu nke sine wave inverter bụ 0.7 ruo 0.9, na ọnụ ahịa a kwadoro bụ 0.9. N'ihe banyere ụfọdụ ike ibu, ma ọ bụrụ na ihe ike nke inverter dị ala, ikike achọrọ nke onye ntụgharị ahụ ga-abawanye, nke ga-eme ka ọnụ ahịa dịkwuo elu ma mee ka ike pụta ìhè nke AC sekit nke usoro fotovoltaic. Ka ọnụ ọgụgụ dị ugbu a na-abawanye, ihe efu ga-abawanye, na arụmọrụ nke usoro ahụ ga-ebelatakwa.
5. Inverter arụmọrụ
Ịrụ ọrụ nke inverter na-ezo aka na oke nke ike mmepụta na ike ntinye n'okpuru ọnọdụ ọrụ akọwapụtara, gosipụtara dị ka pasent. N'ozuzu, arụmọrụ aha nke fotovoltaic inverter na-ezo aka na ibu nguzogide dị ọcha, n'okpuru ibu 80%. s arụmọrụ. Ebe ọ bụ na ọnụ ahịa zuru oke nke usoro fotovoltaic dị elu, a ga-eme ka arụmọrụ nke inverter nke fotovoltaic dị elu, ọnụ ahịa usoro ahụ kwesịrị ibelata, na ọnụahịa nke usoro fotovoltaic kwesịrị ka mma. Ka ọ dị ugbu a, nrụpụta aha nke ndị inverters mainstream dị n'etiti 80% na 95%, na arụmọrụ nke ndị inverters dị ala ka achọrọ ka ọ bụrụ ihe na-erughị 85%. N'ime usoro nhazi n'ezie nke usoro fotovoltaic, ọ bụghị nanị na a ga-ahọrọ ndị inverters dị elu, ma n'otu oge ahụ, a ghaghị ịhazi usoro ahụ nke ọma iji mee ka usoro fotovoltaic na-arụ ọrụ n'akụkụ ebe kachasị mma dị ka o kwere mee.
6. Mpụtapụta nke dị ugbu a (ma ọ bụ ikike mmepụta akara)
Na-egosi ọkwa mmepụta nke ihe ntụgharị n'ime oke ihe ike ibu akọwapụtara. Ụfọdụ ngwaahịa inverter na-enye ikike mmepụta akara, nke a na-egosipụta na VA ma ọ bụ kVA. The gosiri ike nke inverter bụ mgbe mmepụta ike ihe bụ 1 (ie pure resistive ibu), e gosiri voltaji mmepụta bụ ngwaahịa nke e gosiri na mmepụta ugbu a.
7. Usoro nchebe
Onye inverter nwere ezigbo arụmọrụ kwesịrị ịnwe ọrụ nchekwa ma ọ bụ usoro iji mesoo ọnọdụ dị iche iche na-adịghị mma n'oge eji ya eme ihe, ka emebie ihe inverter n'onwe ya na akụkụ ndị ọzọ nke sistemụ ahụ.
(1) Onye njide amụma ntinye n'okpuru voltaji:
Mgbe voltaji ntinye dị ala karịa 85% nke voltaji a tụrụ atụ, onye ntụgharị kwesịrị inwe nchebe na ngosipụta.
(2) Ntinye akaụntụ mkpuchi karịrị voltaji:
Mgbe voltaji ntinye dị elu karịa 130% nke voltaji a tụrụ atụ, onye ntụgharị kwesịrị inwe nchebe na ngosipụta.
(3) Nchedo n'ofe ugbua:
Nchekwa n'elu-ugbu a nke inverter kwesịrị inwe ike hụ na a na-eme ihe n'oge mgbe ibu dị mkpụmkpụ-circuited ma ọ bụ ugbu a karịa ekwe uru, nke mere na iji gbochie ya mebiri site na ịwa elu ugbu a. Mgbe ugbu a na-arụ ọrụ karịrị 150% nke uru egosipụtara, onye inverter ga-enwe ike ichekwa ozugbo.
(4) Nkwenye nkwa nke mkpirisi okirikiri
Oge ọrụ nchekwa obere okirikiri inverter ekwesịghị ịfe 0.5s.
(5) Ntinye ngbanwe polarity nchebe:
Mgbe a na-atụgharị okporo osisi dị mma na nke na-adịghị mma nke ntinye ntinye, onye ntụgharị ahụ kwesịrị inwe ọrụ nchebe na ngosi.
(6) Nchekwa ọkụ:
The inverter kwesịrị inwe nchedo àmụmà.
(7) N'elu nchedo okpomọkụ, wdg.
Na mgbakwunye, maka ndị inverters na-enweghị usoro nkwụsi ike nke voltaji, onye ntụgharị ahụ kwesịkwara ịnwe usoro nchebe oke oke iji kpuchido ibu ahụ site na mmebi oke voltaji.
8. Mmalite njirimara
Mara ikike nke inverter na-amalite na ibu na arụmọrụ n'oge ọrụ ike. Ekwesịrị ijide n'aka na onye ntụgharị ahụ ga-amalite na ntụkwasị obi n'okpuru ibu akwadoro.
9. mkpọtụ
Ndị ntụgharị, ihe nzacha nzacha, ọkụ eletrik na ndị fan na akụrụngwa eletrọnịkị ike na-eme mkpọtụ. Mgbe inverter na-arụ ọrụ nkịtị, ụda ya ekwesịghị gafere 80dB, na mkpọtụ nke obere inverter ekwesịghị gafere 65dB.
